To all who/m it may concern:

Be it known that I, "AUGUs'r citizen of the United States, residing at Philadelphiafln the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in ActuatingMechanism for lVindows, Sashes, Shutters, or the like, of which the following is a specification,reference being had to the accompanying drawings.

The present invention has for its purpose the provision of an improved actuating mechanism especially designed for use in connection with and operating windows, sashes, shutters, or the like,isuch as are customarily pivotally or hingedly hung at their upper portionsto the wall of a store, factory Orother building.

Sashes orjshutters for stores, factories or other similar buildings are. heavy and clumsy, therefore difiicult toopen. and close, hence it is the aim to provide an actuating mechanism, wherein a plurality of togglelinks are employedand are arranged so as to force the shutter or sashoutwardly, and

" to reinforcethe sash in its outward position,

in conjunctionwith means. capable of being operated manually by a single operator, for moving, the sash: or shutter to an open or closed position.

A further purpose is the provision of an.

actuating mechanism, wherein means is included for cushioning the sash orshutter, when moving from an open to a closed position.

Still another purpose is the provision of an actuator wherein means is afforded for effecting an improved jointloetween certain of the toggle links and an endless. actuator proper, whereby the movement of one side of the endless actuator in the one direction and the movement of the otherside in the opposite direction, will cause the toggle links to so operate, as to force the shutter or sash outwardly, and reinforce the same in its outward position.

A further purpose is the provision of an actuator, wherein the endless actuator proper is provided with a fusible joint, which, in case of fire, melts, thereby permitting the shutter to automatically close. The shutter is then free to be opened from the exterior by the firemen, in order to permit access to the interior ofthe building. Also in case .of fire when the factory is not in operation, the fusible joints are broken,

therefore the endless actuator proper is useless, and the shutter or sash may then/be swung open, to permit of access to the fire on the interior.

While the design and construction at present illustrated and set forth isfdeerned preferable, it is obvious that as a result of areduction of the invention to a more practical form for commercial purposes, the invention may be susceptible of changes, and the right tothesechanges is claimed, provided they are comprehended within the scope of what is claimed.

The invention "comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed. a

at. its lower end.

- a portion of the actuator 16, the support 5,

a portion of the closure 3, and the toggle link connections connecting the actuator, the support and the closure or shutter 3, showingv intermediate positions of the toggle links.

Referringmore especiall to the drawings, 1 designates a wall 0 the factory or other building and 2 denotes the window opening, and 3 the sash or shutter for closing the opening. This sash or shutter or other closure is pivotally mounted at 4, either mid way its ends or at its upper end, so that it is the aim to open the sash or shutter at its lower end. In order toaccomplish this operation, a series of toggle links are arranged at different locations and connect the actuator proper and the shutter, so that by movement of the actuator proper, the shutter or sash may be swung outwardly Arranged perpendicularly in the window opening 2 are I beams 5, and secured to theouter face of each beam as at 6,is a bar7.

Suitable brackets 8 and 9 are carried by the opposite side edges of the window opening, and mounted inbearings thereofare shafts 10 and 11.- These shafts have sprockets 12 and 13 mounted thereon, which are engaged by the sprocket chains 14 and 15.

Certain corresponding ends of thesechains are connected by a rod 16, and connected to one end of the chain 14 is a rod 17. Ashort cable 18'is connected to; one end of the rod 17 and this cable 18 is in turn connected to the elongated screw or threaded stem 19.

by means of a swivelled fusible joint 20, which is provided with; a longitudinal groove 21, whose side walls are engaged by the guide 22, as shown in Figures 12 and 13, and which guide is supported by or forms a part of a bracket 23, whereby said screw is thus splined upon said bracket and capable of longitudinal movement only'there 1 1 on, and no rotary movement relatively there 'to. i The sprocket'chain 15 which is connect:

ed to the rod 16 passes over the sprocket 13 and is connected, at 24 to the screw-or threaded stem 19. An internally threaded sleeve 25 is pinned or otherwise secured to the sleeve or extension 26 of the sprocket 27 which is actuatedby the sprocket' chain 28, it being apparent that the sprocket 27 and the internally threaded sleeve 25 rotate as a unit, said sleeve rotating in its bearing 29. The sprocket chain 28 can be actuated in any suitable manner as manually or otherwise, and it will be apparent that the rotation of the sprocket 27 and the sleeve 25 will cause the elongated screw or threaded stem 19 to travel longitudinally in the desired direction, thus imparting a pull or other movement in the desired direction to the connections 18, 19 and 14, thereby actuating the rods 16 and 17 in the desired directions.

Also mounted upon the shaft or pin 10 is a gear wheel '30, which meshes with segment gear 31, which is mounted upon a shaft 32, which is-also carried by the bracket 8. An arm 33 is carried by the shaft 32, and suspended on the arm 33by meansof the rod or link 34 is agravity member 35. I

An eccentric 36 is mounted upon the shaft. 10 to rotate therewith, and engagingsaid eccentric is an eccentric strapz37, which is pivotally connected at 38 to a plunger 39 of a conventional form of pneumatic cushion or dash pot 40. .VVhen the endless actuator member is operated, the chain 14 having been properly moved, the eccentric on the shaft 10 will cooperate with its eccentric ring, and owing to the dash pot or pneumatic cushion, the movement of the endless actuator proper will be cushioned. In other words the endless actuator proper will be prevented from operating suddenly, and through the medium of said brake or cushion and the weight orgravity member 35, the shutter or sash will'be prevented from droppingor closing with a bang, which would otherwise be the case, if it were not for the provision of the cushioning or brake means and the gravity member.

connect the straight line link motion with the window connecting bar. The two blocks or members 48 of each couple are duplicates in construction and may be fastened together in any suitable manner, preferably by means of bolts, such as indicated at 51. These bolts 51 also pass through the openings49. 1

The links 44 are in turn pivotally connected on thebolts 51, and also mounted upon the bolts 51 pivotally are links 53,

which are in turn pivoted at 54 to the bell crank links or levers 55, The bell crank levers or links 55 are in turn pivoted at 56 to the links 57, which are in turn pivoted at 58 to the closure, sash or shutter 23. The arms 59 of the bell crank levers or links 55 are also pivoted at 60 to the links 61 and e r, the latter of which are in turn pivoted at 62' to the links 63, which are pivoted also upon the pins 41. The links 61 are also pivoted to the links 14: at 4-3. Links 65 are pivoted also at 54, and at 41.

It will be seen that upon movement of the endless actuating means proper, for instance movement of the rods 16 and 17 in opposite directions as indicated by the arrows at and 7) in Figure 2, that the various links connecting between the bar 7 and the rods 16 and 17 and the shutter or sash or closure 3, will assume positions shown in Figure 3 of the drawings, thereby moving the shutter or sash to an open position as in Figure 3, and bracing the same. This operation will be accomplished by imparting motion to the sprocket 97 shown in Figure 12. When the shutter, sash or closure is moved to a closed position, it may be cushioned upon the pneumatic cushioning means or dash pot i0, and prevented from closing with a noise.

In case of fire, the fusible swivelled connection between the cable 18 and the screw or stem 19 may become melted, hence rendering the endless actuating means inoperative and in this case the shutter or closure will automatically close. and may be opened from the exterior by the firemen, in order to gain access to the building. 1

In Figure .10 the various links are operable in upright positions, and are connected be tween the I beam and the endless actuator proper. In this figure the bar 7 is slightly modified, in that its opposite arms are offset one above the other, and have depending right angle extension arms 66, and to which certain of the links or the series oi links between the moving rods and the arms of the bar 7 are connected. In this figure the rod 16 has one of its couples provided with a link 67, which in turn is connected to the flange 68 of the shutter or closure or sash 69. which is pivoted at 4- to the wall of the building. It will be noted that when the rods 16 move in one direction and the rods 17 in the opposite direction. namely in this instance in directions toward each other, the links 67 will become angularly disposed and the shutter or sash will be closed, and through the medium of the various link connections between the bar or plate 7 and the rod 16 will act to brace the rods 16 and 17 in their proper positions, when the sash or closure or shutter is opened. One of the couples, for instance 70 of the rod 17 in Figure 10 has an arm 71, which cooperates with one of the couples of the rod 16, to limit the rods 16 and 17 in their movements in directions away from each other.
